Title: A machine for making articles from glass tubing
IPC: C03B23/11
Filed: 1926-10-15
Abstract: 259,990. Favre, P. A. Oct. 16, 1925, [Con vention date]. Addition to 245,120. Making articles from tubing.- Relates to the machine described in the parent Specification for making articles from glass tubing and comprises improvements in the means lor introducing a tube into the holders, and in the means for operating the different parts of the machine. The glass tubes are fed to the machine by two parallel endless chains 27, Fig. 2, which pass over sprockets fixed to a shaft 28 and are provided with teeth 27<a> to hold the tubes. This feeder drops a tube into gapped rings 9 where they are gripped by spring-operated arms 10, as described in the parent Specification. The shaft 28 of the feeder chains is rotated intermittently by a ratchet 24, Fig. 3, and pawl 25, the pawl being moved by a hand lever 19 through a lever 29 and a link 23. The lever 19 also oscillates a lever 31 having at its outer end a bar 32 which enters the gaps in the rings 9 and forces the tube 12 to enter the jaws of the arms 10. The rings 9 are rotated by a shaft 2, and the parts of the tube between the rings 9 are heated by blowpipes 41, Fig. 2, the supply of gas and air for these burners being turned on or off by the movement of a hand lever 38. The lever 38 also controls a clutch 48 that connects the driving-gear to one of two wheels 47 that open or close a lazytongs 15 to which the holders 7 of the rings 9 are secured. Movement of the lazytongs in one direction separates the holders 7 and draws out the heated parts of the glass tube, while movement in the other direction restores the holders to the normal position for receiving a new tube. After being drawn out the rotation of the rings 9 is stopped in the position shown, and the tube is removed from the rings 9 by swinging levers 66. These levers separate the arms 10 and lift the tube on to an incline 70 down which it rolls to shears 74. The shears sever the tube at the drawn out parts and the separated bulbs roll on to a conveyer 80. The levers 66 are moved by links and bell-cranks operated by a hand lever 59. The shears 74 are operated by the hand lever 38. Another hand lever 50 reverses the operations which are initiated bv the movement of the lever 38. In a modified construction, the gapped rings 9 are replaced by pairs of overlapping rotating wheels on which the glass tube rests, another whee. carried by a swinging arm being used to hold the tube in contact with the driving wheels.

Title: Control of nucleation
Inventor: DIFFORD ANTHONY MILES ROBERT
IPC: B01J19/08
Filed: 1967-06-06
Abstract: 1,222,061. Crystal nucleation. IMPERIAL CHEMICAL INDUSTRIES Ltd. 24 May, 1968 [6 June, 1967], No. 25997/67. Heading C1A. [Also in Divisions B1 and C2] The number of crystal nuclei formed in a supersaturated solution is controlled by controlling the number of free OH radicals in the solution. The number of free radicals may be reduced by shielding from natural radiation or adding a scavenger. Scavengers specified are hydrogen peroxide, hydrazine, hydroxylamine, isopropyl alcohol, phenol, or quinol; or the iodide, nitrate, ferrous, or ferrocyanide ion. The number of free radicals may be increased by artificial radiation, far U.V. photolysis, decomposition of hydrogen peroxide or an organic peroxide in the solution, or reaction between ferrous ion and hydrogen peroxide in the solution. Artificial radiation may be effected by a cobalt-60 γ-emitter, or an α- or #-emitter in conjunction with a radio-active element dissolved in the solution. Shielding from natural radiation may be combined with artificial increase in the number of free radicals. In the examples, the supersaturated solution results from double decomposition (for insoluble salts) or mere cooling (for soluble salts), specified salts being ammonium sulphate; sodium chloride; calcium carbonate or sulphate; strontium carbonate; barium fluoride, phosphate or sulphate; lead chloride or sulphate; zinc phosphate; silver bromide or iodide.

Alternatively, annealing at 500-700‹ C. may be effected after cooling to room temperature. In the preparation of the alloy, instead of titanium, ferro-titanium, which may contain aluminium, silicon, copper and manganese, may be used and, instead of cobalt, ferro-cobalt, which usually contains copper. The silicon content of the ferro-titanium ahould be such as to yield a silicon content in the alloy of less than 1 per cent. The Specification as open to inspection under Sect. 91 refers to a slightly wider range of nickel content. This subject-matter does not appear in the Specification as accepted.

Abstract: 644,610. Thermionic valves. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Sept. 29, 1947, No. 26292. Convention date, Oct. 4, 1946. [Class 39 (i)] A device for adjusting axially the position of the cathode in a coaxial conducting part 2 of an electron discharge tube comprises a spring 5 acting upon cathode 1, a wire 4 so associated with the cathode as normally to oppose its displacement, means for passing a current through the wire to vary its length and hence the position of the cathode, and straps 6 to guide and position the movable cathode. In Fig. 2, the cathode bears against washer 3 which is moved by the expansion of wire 4. When the heating current is cut off from wire 4 the washer is withdrawn, but the cathode remains in its new position, held by the non-elastic straps 6. In a modification, Fig. 3 (not shown), the cathode is clamped to the washer 3 so that it moves back when the wire 4 contracts and continuous adjustment is possible. The wire 4 may be coated with an appropriate substance enabling it to serve as a getter.

Abstract: 403,487. Actuating controllers. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, SCARF, C. T., Woodcroft, Rednal, Worcestershire, and BERTLES, E. J., 1, Norbury Road, Eccleshill, Bradford, Yorkshire. Sept. 22, 1932, No. 26383. [Class 38 (iii).] An electric-motor starting-rheostat is operated by an auxiliary motor whose speed is dependent upon the position of the moving member of the rheostat. As shown, a continuously running pilot-motor 1 operates the shaft 4 of a liquid starting-rheostat through a clutch 2. Anticlockwise movement of an operating handle 7a brings a contact 6 into engagement with a contact sector 5 carried by the shaft 4, thereby energizing a coil 3 to close the clutch 2 until the starting resistance has decreased to a value determined by the position of handle 7a, the speed of the pilot-motor 1 being simultaneously reduced by a shunt regulator 8 operated from the shaft 4.

Biological applications e.g. zone electro-phoresis including blood analysis are referred to The sample may be an electro-phoresis strip secured magnetically to the apparatus. Integration is achieved by producing pulses having a recurrence frequency proportional to the detector voltage and storing them, e.g. in a counter. The signal may be mathematically treated to indicate directly the value being measured, logarithmic conversion and inversion being exemplified. Clock pulses are used both for control and for driving, the traversing motor, separate motors being provided for sample scanning and recording, the limits of scanning being determined by up-down counters and limit switches.
